<p>[QUOTE=&quot;joesmom, post: 59582, member: 934&quot;]Just to go a little further on the cause of weak/poor strikes from various mints...From <i>Silver Dollars and Trade Dollars of the United States</i>:&nbsp; </p><p><br /></p><p>&quot;A very important factor in striking quality among Morgan dollars was the curvature of the basining wheel used to polish new dies at the mints.&nbsp; The Carson City mint dies were the most convex, bringing the centers closer together, but leaving the rims further appart.&nbsp; This is a prime reason why the Carson City mint dollars have strong centers but weak rims.&nbsp; The New Orleans mint dies were often too flat, causing strong rims but weak centers.&nbsp; The Philadelphia and San Francisco mint dies were the most correctly basined, and produced the coins most consistently struck in a &#039;normal&#039; way.&quot;[/QUOTE]</p><p><br /></p>
